Abstract

Rooted cuttings (stecklings) from 40 different clones, and seedlings from one seed source of Norway spruce (Picea abies L. KARST.) were planted on 7 contrasting test sites in northern Germany. Survival rates and total heights (Ht) were observed at ages 3, 5, 8, 10, 13 and 17 years. Diameters at breast height (dbh) were also measured at age 17. Test site means for survival rate ranged from 81% to 95%, except site Kattenbuhl (73%). About 70% of all deaths on the test sites occured within the first four growing seasons after outplanting. Clones taller in nursery tended to show higher death rates in the early years in the field than Shorter clones. There were significant differences among the test sites in survival rates, but no rank interactions over the years. Seedlings and stecklings from the same origin (i.e. Westerhof) showed similar survival rates at all the test sites.
